Proposed Stiffener Spacing Requirements for the Seismic Design of Short Links in Eccentrically Braced Steel Frames

Links in eccentrically braced frames (EBFs) are designed with transverse web stiffeners to achieve the desired seismic performance targets established in current design standards. Prior studies have suggested that stiffener spacing requirements in the stan ...

Energy dissipation in fiber-polymer composites adhesive joints under cyclic loading

Ghazaleh Eslami

Sustainable development has emerged as a paramount consideration in various fields of industry, including construction, to preserve the environment and its finite resources. Lightweight structures, such as fiber-polymer composite structures, address both s ...

Seismic vulnerability assessment of free-standing massive masonry columns by the 3D Discrete Element Method

Jinwoo Kim

Free-standing masonry column is a recurrent typology of built cultural heritage. Usually raised without seismic design, columns are subject to intense rocking and overturning under strong ground motions. In this paper, a strategy to assess their seismic vu ...

Three-dimensional physics-based earthquake ground motion simulations for seismic risk assessment in densely populated urban areas

Alfio Quarteroni

In this paper we describe a mathematical and numerical approach that combines physics-based simulated ground motion caused by earthquakes with fragility functions to model the structural damages induced to buildings. To simulate earthquake ground motion we ...

Origin of the Co‐Seismic Variations of Elastic Properties in the Crust: Insight From the Laboratory

Marie Estelle Solange Violay, François Xavier Thibault Passelègue, Mateo Alejandro Acosta, Federica Paglialunga

Seismological observations highlighted that earthquakes are often followed by changes in elastic properties around the fault zone. Here, we studied the origin of these variations using stick-slip experiments on saw-cut granite samples presenting different ...

Composite steel beam database for seismic design and performance assessment of composite-steel moment-resisting frame systems

Dimitrios Lignos, Ahmed Mohamed Ahmed Elkady, Hammad El Jisr

This paper discusses the development of a publicly available database of composite steel beam-to-column connections under cyclic loading. The database is utilized to develop recommendations for the seismic design and nonlinear performance assessment of ste ...

Improved Seismic Design and Nonlinear Modeling Recommendations for Wide-Flange Steel Columns

Dimitrios Lignos, Ahmed Mohamed Ahmed Elkady

This paper presents the findings of parametric finite-element (FE) simulations of more than 50 wide-flange steel columns under cyclic loading. The column sizes, which are mostly highly ductile according to the current design practice in North America, are ...

Structural Resilience through Model-Based Data Interpretation: From Building to City-Scale Post-Seismic Assessment

Ian Smith, Pierino Lestuzzi, Yves Sylvain Gilles Reuland, Lorenzo Diana

Earthquake-design approaches in regions with low to medium seismic hazard often focus on the protection of inhabitants. Therefore, some structural damage is accepted. In addition, large parts of the building stock have usually been built without considerin ...

The role of uncertainty in dam failure frequency estimates: a conceptual case study

Anton Schleiss, José Pedro Gamito de Saldanha Calado Matos

The return period of combinations of events that are relevant to dam risk analysis is very high. It falls in a range of hundreds to millions of years, but remains hard to quantify with precision. Deterministic approaches to dam safety assessment typically ...

Seismic vulnerability assessment at urban scale: state of the art and perspectives

Lorenzo Diana

Italian territory is particularly sensitive to seismic actions. The Amatrice earthquake on August 24th 2016 confirmed this aspect. Such an event, nothing but extraordinary, has been able to cause huge and tragic damages. The direct knowledge of building fe ...

Validation of a FEA model of structural response of RC-cantilever beams strengthened with a (R-) UHPFRC layer

Eugen Brühwiler, Emmanuel Denarié, Hamid Sadouki

This paper focuses on modelling of structural response of RC cantilever beams retrofitted with a thin layer of Ultra High Performance Fibre Reinforced cement-based Composite (UHPFRC). The complex cracking phenomenon of the resulting RC-UHPFRC composite sys ...

Seismic vulnerability assessment at urban scale for two typical Swiss cities using Risk-UE methodology

Pierino Lestuzzi, Angelo Garofano, Patrick Bischof

This paper contains a seismic assessment at urban scale of the cities of Sion and Martigny in Switzerland. These two cities have been identified for the present research based on their importance regarding size and the characteristics of the building stock ...

Seismic Behaviour and Design of Mixed RC-URM Wall Structures

Alessandro Paparo

In several countries of central Europe, many modern residential buildings are braced by reinforced concrete (RC) and unreinforced masonry (URM) walls coupled with RC slabs. Such mixed constructions, in fact, behave better under seismic loading than buildin ...

Performance limits of brick masonry spandrels

Katrin Beyer

Spandrel elements in unreinforced brick masonry buildings with timber floors consist of a masonry spandrel supported by either a timber lintel or a masonry arch. When subjected to seismic loading, the force-deformation relationship of such spandrel element ...

Fragility Functions for Seismic Risk in Regions with Moderate Seismicity

Marcelo Rafael Oropeza Ancieta

The seismic assessment of existing buildings has been underestimated in regions with moderate seismic hazard, such as the North-West Europe. Strong earthquakes, such as the 1356 Basel earthquake, already occurred in such regions and caused severe damage. T ...

Fragility functions for seismic risk in regions with moderate seismicity

Pierino Lestuzzi, Marcelo Rafael Oropeza Ancieta

Current seismic risk evaluations are mostly based on approximate vulnerability curves. Damage prediction is improved by considering structural characteristics of building. Such improved fragility functions do not exist for many structures, especially in co ...
